IMPROVEMENT IN PAPER BOXES.

Specification forming part of Letters Patent No. 177,279, dated May 9, 1876; application filed March 25, 1876.

To all whom it may concern Be it known that- I, REUBEN BITTER, of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Folded Paper Boxes; and do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specification, in which- Figurel is a plan view of the blank or pattern of the box; Fig. 2, a plan of the box folded; Fig. 3, vertical. transverse section; Figs. 4 and 5, perspectives of my invention.

My improvements have reference to the following points: first, to the form of the blank, which is substantially rectangular, with two short projecting tongues at one end, and two corresponding slots at the other end, to receive said tongues; secondly, to forming both ends of the box exactly alike, each end heing closed by five flaps, which extend entire- "iy across from side to side, thus giving, without undue waste, a quintuple thickness,

v and corresponding strength, to these parts of the box, and preventing the same from being pushed out by internal pressure or expansion; thirdly, to means for taking hold of the end flaps when the box requires to be opened.

7 Referring to the accompanying drawing, A

represents the blank, which is cut, in the *irst instance, in a rectangular form, with straight edges, a, a at right angles to 19h other, one of said edges having short ecting tongues a M. The blank is creased i-tudinally at b b, so as to fold thereon to .m the ends, and is also creased laterally the lines 0 c, which are the dividing-lines between the sides. The blank is also cut laterally from the edges a a to the creases 12, forming flaps d d e f, the said flaps 0 being beveled or tapered on their ends, and creased at e, to form tongues 6 0 for use as hereinafter specified. g g are slits for the reception of the locking-tonguesv a said slits ,being formed in the flaps (1. his a looking or space or area of the end of the box, andcompletelyclosing the same. The flaps e are then turned in, their tongues 6 being passed between the edges of the flaps cl (1 f and the sides hh- The'opposite flaps e are then turned over, and, their tongues 6 being passed in the slits between the card h and the side it, the box is completely closed.

If desired, the card it may be wholly dispensed with, and the tongues e merely inserted in slits k coinciding with the creases b, and tongues a on each of the edges a instead of on one edge only, may be employed. v

To enable the flaps e to be readily taken hold of when it is desired to open the box, semicircular slits t' may be cut in said flaps, forming short tongues Ia. These tongues, projecting in the manner shown in the drawing, will form means for drawing out the flaps e 0 when it is desired to open the box.

What I claim as my invention is 1. The blank A,'rectangular in form, having the projecting tongues of a and outer slit to form the flaps d d e f, substantially as shown and described.

2. A folded paper box, locked on theend V flaps by means of the tongues a a and slits g g, formed in or upon said end flaps, the same being produced from the outermost wings of the blank, substantial y as shown and described.

3. A folded paper box having five end flaps, each of said flaps completely covering the end of the box, and two of the flaps at each end being formed with tongues c 6 substantially as shown and described. I e 5 4. A folded paper box, looking onthe end flaps, the body of said bix having three single sides and one double thick side, the ends of said box be ng' .closed by qnintnple flaps, each of said flaps cznnpletely covering the end of the box, and two of the flaps at each end being forzned with inserting or locking tongues, Substantially as shown and described.

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of March, 1876.

REUBEN BITTER.
